Abstract

Et rørhåndteringssystem omfatter en rørløfter som kan bringes til å bevege et rør (412) fra en horisontal lagringsstilling til en skråstilling. l skråstillingen er en øvre ende av røret nær inntil et hevet boredekk (24) i en borerigg (12), og røret danner en vinkel mellom horisontalt og vertikalt. Rørhåndteringssystemet omfatter også et føringssystem (500) som kan bringes i inngrep med røret og styre sidebevegelse av røret når det beveges fra å være understøttet i skråstillingen av rørløfteren til en vertikal stilling understøttet av boreriggen.A pipe management system comprises a pipe lifter which can be caused to move a pipe (412) from a horizontal storage position to an inclined position. In the inclined position, an upper end of the tube is adjacent to a raised drill floor (24) in a drilling rig (12), and the tube forms an angle between horizontal and vertical. The pipe handling system also comprises a guide system (500) which can be engaged with the pipe and control lateral movement of the pipe as it is moved from being supported in the sloping position of the pipe lifter to a vertical position supported by the drilling rig.
